CVE-2012-4792

Microsoft Internet Explorer Use-After-Free Vulnerability

What is affected

Vendor Microsoft
Product Internet Explorer
Weakness CWE-416

The vulnerability

Microsoft Internet Explorer contains a use-after-free vulnerability that allows a remote attacker to execute arbitrary code via a crafted web site that triggers access to an object that (1) was not properly allocated or (2) is deleted, as demonstrated by a CDwnBindInfo object.

Required action

The impacted product is end-of-life and should be disconnected if still in use.

US federal civilian agencies were required to act by 13 August 2024 under BOD 22-01. The deadline is a compliance date, not a measure of severity — it says nothing about how dangerous the flaw is to anyone else.
